NAICS 336612 – Boat Building encompasses the design, construction, and repair of military and government-operated vessels, including patrol boats, landing craft, harbor support vessels, and specialized watercraft used for maritime security, logistics, and special operations. This sector involves precision fabrication using composite materials, aluminum alloys, and marine-grade steels, alongside integration of propulsion systems, navigation electronics, and mission-specific payloads such as surveillance suites or weapon mounts. As part of the broader defense maritime industrial base, boat building supports the U.S. Navy, Coast Guard, and other federal agencies requiring rugged, low-signature, and high-mobility watercraft for coastal, riverine, and littoral operations. The work demands compliance with stringent military specifications, including survivability standards, anti-corrosion protocols, and supply chain traceability requirements. Top contractors in this space include BHPE LLC, RE-ENGINEERED BUSINESS SOLUTIONS, INC, and ALLOY SLING CHAINS, LLC, a mix of small businesses and specialized mid-tier firms with expertise in naval architecture, modular vessel construction, and defense-grade component fabrication. These firms often serve as niche suppliers or prime contractors for tailored, low-volume programs requiring rapid prototyping and agile production cycles. The Department of Defense is the primary federal buyer, driving demand through naval modernization initiatives, Coast Guard fleet renewal, and special operations watercraft procurement. Programs focus on enhancing domain awareness, rapid deployment capability, and force protection in contested maritime environments. The competitive landscape is characterized by high barriers to entry due to technical specialization, security clearances, and certification requirements, creating concentrated opportunities for firms with proven naval manufacturing experience and supply chain resilience. Growing emphasis on distributed maritime operations and unmanned surface vessels is expanding demand for adaptable, scalable boat platforms.
Small Business Size Standard
The SBA threshold that decides who can bid NAICS 336612 work as a small business.
The SBA cap for this NAICS (13 CFR 121.201). A business at or under it can self-certify as small for work in this code, which is what makes it eligible for a small-business set-aside. The cap is set per NAICS, so the same company can be small in one code and not in another.
13 CFR 121.201, effective January 1, 2026. The SBA revises the table roughly once a year.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.
